I found this shit at an amusement park arcade when I was a teen and it was the coolest shit ever
It didn't even have the fist guards so you had to hit it bare knuckle
Needless to say, the next time I went they had already gotten rid of it
You just hit the pads as they flip up and at some point they all flip up and you unleash a flurry of punches
Gave me an appreciation for Fist of the North Star, wish I could play it again
